To all whom it may concern:

Be it known that we, IVILLIAM GRAVER and .ALEXANDER MACDONALD GRAVER,both citizens of the United States, and residents of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Tank-lVagons, of which the following is a clear,full, and exact description.

Our invention relates to tank wagons, and particularly the kind used forconveying tar, bitumen, and other heavy hydro-carbons in a liquid state.

The object of our invention is to construct, in an economical manner,the supportinggear for the tank largely of structural metal, in suchmanner that both rigidity and strength is imparted to the same.

A further object of our invention is to so construct the fire-chamberand smoke-flue extending therefrom longitudinally under the tank, that,when it is desired to replace or repair the parts of the same, it can bedone without affecting the connection of the sides thereof with thetank; substantially as hereinafter fully described and as particularlypointed out in the claims.

In the drawings :--Figure 1 is a side elevation of our invention showingthe nigh wheels removed. Fig. 2 is a rear end elevation. Fig. 3 is afront end elevation. Fig. 4 is a transverse vertical section of the tankand fire-chamber. Fig. 5 is a perspective view of the tank-lugs. Figs. 6and 7 show side and end views, respectively, of the rear axle, bolsterand elements attached to and supporting the sidesills. Fig. 8 is adetail view showing a transverse section through the smokebox.

Referring to the drawings A represents a tank, which is, preferably,cylindrical, and extends from in front of the front axle of the wagon toa point a suitable distance to the rear of the rear axle. This tank haslongitudinal channel-beams a, a, secured to its bottom on each side ofthe longitudinal vertical plane intersecting its axis, which extend fromnear the rear end of the tank to a point a suitable distance in front ofthe front end of the same. These channel-beams are so arranged thattheir flanges project outward, and, to the rear of the rear axle, theoutwardly flanged upper edges of the sheet metal side-walls 2, 2, of thefire-chamber B are riveted or otherwise secured thereto. Between thefront side of the fire-cham- Specification of Letters Patent.

her and their forward ends, the lower flanges of these beams areconnected by a downwardly curved horizontally disposed plate 3, thecurvature of which is struck from the center of the tank, and thesechannel-beams a, a, and plate 3 form a flue under the tank extendingfrom the fire-chamber to the smoke-box in front of the smoke, which boxwill be hereinafter more fully described. The upper edge of thefront-wall 4 of the firechamber is flanged forward, and laps under andis riveted or otherwise secured to the rear edge of plate 3, and theupper edge of the rear sheet metal wall 5 of the fire-chamber is rivetedor otherwise secured to the vertically disposed portion of a transverseangle-iron strip 6, whose horizontal portion is riveted or otherwisesuitably secured directly to the tank. As thus constructed the walls ofthe fire-box are not connected directly to the tank and can be removedfor repairs or replacement-s without affecting the tank whatsoever. Theremaining features of this fire-chamber B are constructed in accordancewith well known principles, to which further reference is deemedunnecessary.

The portion of the channel-beams a, and plate 3 extending in front ofthe tank form the sides and bottom .of a smoke-box, that is covered overby a transverse horizontal plate 7 which latter has its side edgesriveted or otherwise secured to the upper flanges of said channel-beams;its rear edge secured to the adjacent head of the tank by a transverseangle-iron strip 8, and its front edge provided with a transverseangleiron strip 9 by means of which the front-plate 10 of the smoke-boxis riveted or otherwise secured to the same. The front end edge of plate3 has a transverse angle-iron strip 11 secured to its underside, and thelower edge of plate 10 is secured to this strip 11. By using bolts andnuts to secure plate 9 in place, it can be easily removed when de sired.A pipe 12 is secured to and leads from an upwardly flanged opening inthe center of plate 7 which inclines upwardly toward the side of thewagon and then vertically so as to make room for the drivers seat andfoot-rest, substantially as shown in Fig. 3 of the drawings.

The tank is supported in a substantially horizontal position by means oftank-lugs 13, which latter are shown'in perspective in Fig. 5 of thedrawings, and consist, pref.-

erably, of a cast metal segmental plate, that is riveted or otherwisesecured to the sides of the tank below its center, and have downwardlyprojecting triangular shaped webs 0, the lower horizontal edges of whichare connected by a horizontal foot 14, that rests upon and is secured tothe upper flanges of the I-beam side-sills D, D. As shown in thedrawings, two pair of these tank-lugs are used, one in the transversevertical plane of the rear axle, and the other in a transverse verticalplane to the rear of the front axle. I prefer to reinforce the sides ofthe tank in the transverse plane of lugs 13 by securing to their innersurfaces vertically disposed segmental strips of angleiron, 15, thatextend from a point in the vicinity of the channel-beams a to a pointabove the plane of the tank-lugs, as shown. The side-sills are placed ina longitudinal vertical plane outside of the channel-beams a, and theyextend from a short distance to the rear of the tank to a short distancein front of the same, and have their extended ends connected bytransverse angle-iron bars or end-sills m, m, the vertical portions ofwhich bear against the ends of the tank, and assist in preventing thelongitudinal displacement of the same, or the consequent shearing of therivets or bolts by means of which the tank-lugs are connected to saidside-sills. The rear axle E of the wagon is located just in front of andin a horizontal plane just above the bottom of the firechamber, and itis reinforced by a superposed longitudinal bar 17, the ends of whichabut against flanges 16, 16, of the spindles. Secured upon the ends ofbar 17 are posts 18, whose lower ends are bent outwardly to form thefeet that rest upon the bar and are, preferably, secured thereto byrivets 19, and by the inverted U-bolts 20. The upper ends of the posts18 are bent outwardly in the same direction as their lower ends, andsupport the sills, to the lower flanges of which they are, preferably,riveted. The lower screw-threaded ends of the U-bolts 20 extend throughthe center of length of a longitudinally disposed brace H, which latterpasses under the axle, and has its ends extended upward at a suitableangle to sills D, to which they are riveted or bolted. The sills D arealso braced to pre vent any independent lateral movement thereof, bymeans of the transverse braces 21, which consist of a somewhat l-shapedmetal bar whose ends are bent vertically so as to bear flat against theinner circumference of the webs of the sills D, with their extremitiesbearing up against the underside of the upper flange thereof, in whichposit-ion they are riveted to the sills. From the sills this transversebrace inclines downward toward the center of the axle where it isprovided with a horizontal portion that rests upon and is secured to thereinforcing bar 17 of the axle by means of rivets, and to said axle byinverted Ushaped bolts or clips 22, whose lower screw-threaded endsextend down through a suitable plate 23, and are tightened by means ofnuts on their lower ends, substantially as shown. If de sired, braces 21and post 18 may be slightly wider than the axle, and may be providedwith slight recesses in its edges for the accommodation of the bolts orclips 20 and 22, so that when the same are properly assembled,transverse movement thereof will be absolutely prevented.

The forward end of the sills D are supported by a series of two or threetransverse Lbeam bolsters 7c, the ends of which have their upper flangesriveted or bolted to the lower flanges of the sills, and the centralportions of which are bent downward to enable them to pass under theplate 3 of the smoke-flue, and have the upper circular member K of thefifth wheel secured in any suitable manner thereto.

\Ve do not claim any invention in and to the construction of therunning-gear connected with the front wheels of our tank wagon, and,therefore, do not consider a more extended reference thereto necessary.
